PAPER-BOX MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 545,219, dated August 27, 1 895.

Application filed November 22, 1894. Serial No. 529,587. (No model.)

To a-ZZ whom, it may concern.-

Be it known that 1, JOHN C. BLUNDELL, of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Paper-Box Machines, of which the following is a specification.

The object of this invention is to providea machine which will apply to paper or pasteboard or wooden boxes the paper fly or flap commonly employed to cover the contents of the box and usually fastened along one edge to one side of the box on the interior, its remaining portion being left free to be folded in and out.

A machine embodying the invention employs a suitable support for that side of the box to which the fly or flap is to be attached; means for feedingthe paper of which the fly is formed in a continuous strip and severing the same in proper lengths; means for applying paste along the forward edge of the paper; means for advancing the pasted edge into the box over the side thereof which rests on the support; means for sealing the paper to the box by pressure applied over the pasted edge,

and means for folding the fly over and into the box after it has been sealed.

The invention therefore consists in a number of novel combinations of elements, which are recited in the appended claims.

An embodiment of the invention is illustrated in the accompanying drawings, which form part of this specification. I

In said drawings, Figure 1 shows aside elevation of the machine. Fig. 2 showsa top plan view of the machine. Fig. 3 shows a central longitudinal section of the machine. Fig. 3 showsa similar section of part of the machine withaboxrepresented undertreatment. Fig. 3 isasectional detail of a certain paste-holder and polygonal roller therein. Fig. 4 shows a partial side elevation and partial longitudinal section of the machine, illustrative of a different stage of its operation than seen in the preceding figures. Fig. 5 shows a rear elevation of the machine. Fig. 6 shows a section on line 6 6 of Fig. 2. Fig. '2' shows a section on line 7 7 of Fig. 6. Fig.8 shows aperspective view of a certain knife-carrier. Fig. 9

Fig. 15 shows a section on line 15 15 of Fig. 2, the scale being onlarged. Fig. 16 shows edge and side views of a clutch member appearing in section in Fig. 15. Fig. 17 shows a box in perspective with the fly attached. 18 shows a. similar View with the fly folded into the box.

In order that it may be first understood just what the machine here illustrated is designed to do, reference is to be had to Figs. Hand 18, wherein the reference figure2 designates a box of any ordinary type. It may be for containing shoes, hosiery, underwear, cigars, confectionary, or any other commodity. The reference-figure 3 designates a piece of paper, which may be termed a fly or flap, and which is secured along one edge to the interior surface of one side of the box adjacent to the edge of the same and is designed to be folded over into the box, as shown in Fig. 18.

In the description of the machine here shown I will first enumerate the elements which constitute the direct supports for the work and those which act directly on the work, and thereafter give a description of the means employed to impart the necessary movements to the latter.

The letter a designates a horizontal table on which the box rests, as shown in Fig. 3, and is held between guides at.

b b designate feed-rollers between which the paper forming the fly passes.

c designates a knife for severing the paper.

61 designates a paste-applying device; 6, a sealing device; f, a folder.

The feed-rollers and the knife are mounted on acarriage arranged to move longitudinally of the machine, so as to provide for adjustment to cut difierent lengths of paper, and the said carriage is of the followingconstruction: A base-plate g has position between the sides 72. of the supporting-frame of the machine, and is cut out to accommodate the lower roller 12, and plates or flanges g are fastened on top of the plate 9 at each end and ers b and bare intermeshing gears b and 19 which are arranged to be connected with their respective rollers through friction clutch devices, so that when turned in one direction they drive the rollers, and when turned in the reverse direction they rotate independently of the rollers. Each gear is formed on each side with bosses I), (see Fig. 14,) having inclined faces terminating in abrupt shoulders. There are two disks b mounted loosely on the journal of the roller at different sides of the gear and formed with coacting inclined surfaces, and two other disks b are affixed to the roller-journal next the disks b Upon -turning the gear in one direction the coaction of its inclined face with those of the disks 19 causes the latter to be crowded into frictional engagement with the disks o sothat the roller is turned with the gear. When the gear is turned in the opposite direction, the disks b slip between the disks Z1 and no movement is imparted to the roller.

An oscillatory motion is imparted to the gears 19 b through the following-described connections with the main or driving shaft 2 of the machine: A segment I) meshes with the lower gear b and is journaled in a bearing on one of the hangers g", and said segment carries a turn-piece 218, through which a pitman-rod Z2 may slide, and in which it is fixed by a nut 11 The opposite end of said pitman-rod is mounted on a wrist-pin '1)", carried by a slide Z1 which may be adjusted in a radial slot of a disk b by means of ascrew I). Said disk is concentric with the drivingshaft 3 and is rigidly connected therewith by being affixed to a wrist-pin e on a crank e fastened to the shaft.

In addition to the primary movement imparted to the feed-rollers through the means just described, which only serves to feed the paper up to the box and over the pastor d, a supplemental movement of said feed-rollers is provided for to advance the pasted edge of paper into the box, and the means for producing this supplemental movement of the feed-rollers are of the following description: A clutch device similar to that already described is applied to the end of the lower roller 1) opposite to that carrying the gear, said clutch device comprising a double-faced collar m (see Fig. 15) loose on the journal of the roller between two loose disks m with correspondingly-formed faces, and disks m affixed 13y tightening nuts on said bolts to the journal and designed for frictional engagement with the disks m. The collar m has a pendent arm m carrying a turn-piece through which a pitman-rod m may slide, said rod being fixed by means of a set-screw or nut. This pitman-rod is connected with an arm m which is affixed to a short rock-shaft m in a bearing m depending from one of the bearings for the main shaft 2', and another arm m affixed to said rock-shaft, carries a roller in engagement with a cam-groove m in a disk m affixed to the shaft After the paster has performed its work the irregular portion of the cam-groove m enters into engagement with the roller and the feed-rollers are operated through the connections described to advance the pasted edge of paper into the box.

' The knife 0 is fastened to a sliding frame 0', which fits in vertical ways in the hanger r, and in cutting the knife passes up beyond the plate 9 and by the lower edge of a coacting-bar c fastened to the plate g. The slide 0 is reciprocated through the following-described connections with the driving-shaft: A rod 0 extends between the end bars of the frame 0 and carries square blocks o which engage slots in arms a affixed to a shaft o journaledin the hangers g. 'A pendent arm 0 affixed to said shaft, carries a turn-piece 13*, through which a pit-man-rod 0 may slide, and in which the latter is affixed by means of a nut 0 The opposite end of said pitman-rod connects with an eccentric c on the shaft 2. A horizontal support is arranged to extend from a point in front of the knife to a point back of the fo'lderf, and in order to have this support accommodate itself to different positions of the carriage it is of the following construction and arrangement: A flexible sheet i, of suitable material, is fastened at one end to a stationary support 2" immediately back of the folder f and at its opposite end to the rear end of the frame at 71 somewhat below the plane of the support 1". Ears on the hangers 9 support a rod or roller 2' and overhanging brackets t fastened to the bar 0 support.a similar rod or roller F. The sheet 2' is carried around these rods or rollers t and i being passed in front of the rod i and behind the rod i so that a stretch of the sheet extends horizontally between the support 1" and the rod 2' and another stretch of the sheet extends vertically between the two rods, and still another stretch extends horizontally between the rod 2' and the support 1' passing through the frame 0. This disposition of the sheet is maintained at all times, notwithstanding movement of the carriage, and so there is valways a horizontal stretch extending from a point in front of the knife to a point immediately back of the folder, which stretch constitutes the horizontal support heretofore mentioned for the paper fed forward by the rollers.

The paste-applying device (1 is in the form of a rectangular bar, which is designed to ICC IlC

work pastthe end of the table a, with its outer longitudinal edge uppermost, and is fastened to another bar (1., whose main portion is round in cross-section and has its ends turned down to journal in boxes fitting longitudinal slots in a pair of curved arms d affixed to a shaft (1 Another shorter arm (1, affixed to said shaft, is connected by a rod d with an eccentric d on the driving-shaft a. It will be seen that through these connections the pasting bar will be reciprocated vertically.

A paste-potj is supported at the lower ends of hangersj, fastened to the frame of the machine, and through this pot extends a polygonal bar or rod j which is designed to be partially submerged in the paste, and from whose exposed sides the bar cl is to take the paste.

In order to have the bar d take the paste in this way, it is evident that said bar must be reversed as it descends, so that its outer edge will come down upon the polygonal rod, and the means shown'for accomplishing this are of the following description: Plates 7c are fastened to the inner sides of the hangersj and are formed with corresponding cam-slots is, each having straight vertical end portions and a central offset portion. Disks k ,,fastened to the journals of the bar of, carry rollerequipped crank-pins k engaging the slots in. While these pins are in the straight portions of the slots, the bar d is held in a vertical plane with its outer edge horizontal. When the pins enter the central offset portions of the slots, the bar will be turned and reversed. Thus when the'bar descends it is maintained upright until the pins enter the offset central portions of the slots, whereupon the bar will be turned so that when the pins reach the apices of the offset portions the bar will have a horizontal position, and in the traverse of the pins through the remainder of the offset portions the bar will be turned downwardly, so that when the pins enter the lower straight portions of the slots the bar will be in a vertical plane with its outer edge downward and prepared to bear squarely against the polygonal rod. The same thing takes place in the upward movement of the paster, so that the outer edge is uppermost to do the pasting of the paper.

The polygonal rod 9' is turned step by step to present its sides successively to the pasting-bar withfresh supplies of paste, and the means shown for accomplishing this are of the following description: A ratohet-wheelj is affixed to the journal of the rod, and an arm j is loosely mounted on this journal and carries a pawl j in engagement with said ratchet. A pitman-rod j connects the arm j with an eccentricj on the driving-shaft z.

The sealing device a is in the form of a face-plate fastened to a casting e which is supported between a pair of arms 6, pivoted on studs c fastened in the sides of the frame,

5 the said arms being of angular shape and their lower ends being connected by rods c with arms 6' affixed to a shaft 6 One of these arms c has an angular extension e, which gives it the form of an elbow-lever, and said extension is connected by a rod e with the wrist-pin c.

Through the above-described means the sealing-plate e is swung up and down and at the proper time brought to bear on the paper where it lies over the inner side of the box. (See Fig. 3.)

The folderf is in the form of a plate, which normally rests between the pasting-bar (Z and the support 1', with its upper surface flush with that of the table Ct and sheet 11. Said plate is fastened to levers j, which extend along the sides of the table and are pivoted intermediate of their ends to armsf loosely mounted on a rock-shaft f One of said arms f has an angular extension f carrying a roller in engagement with a cam-groove f (see Fig. 18) in the disk m The forward ends of the levers f are connected by rods f with arms f affixed to the rock-shaft f and one of said arms is formed with an angular extensionf", carrying a roller in engagement with a cam-groove f in a disk f affixed to the shaft 2. The coaction of this camgroove f with the roller on the arm f produces oscillation of the lever-sf and an upward movement of the folder against the paper. When the folder is elevated, as shown in Fig. 4:, the irregular portion of the camgroove f comes into play and, by turning the arm f f', moves the folder forward and into the box, so as to carry the folded-over paper thereinto.

The details of the machines construction having now been described, a brief statement of its general operation will be given.

The paper is supplied to the feedrollers in a continuous strip, and an action of the primary feed mechanism advances the forward edge of the paper to a point in vertical alignment with the front side of the pasting-bar (Z. This primary feed then ceases, and while the paper remains at rest the bar cZ rises and applies paste along the edge of the paper, and then said bar recedes. Now the supplemental feed mechanism acts to carry the pasted edge of paper into the box, and the paper is again left at rest, while the knife csevers it. After this the sealingplate 6 comes down and presses the pasted portion of paper against the side of the box, and after it has receded the folder f rises, taking the paper with it, and then moves forward, pushing the paper into the box.

It is evident that the invention is capable of embodiment in different forms than that here shown.
